Toshiba America Medical Systems Introduces New MR Technology

Toshiba America Medical Systems (Toshiba) has introduced Variable True Rate Angiography with Combined Encodings (V-TRACE), an MRA sequence available on all Vantage Titan and Vantage Atlas MR systems, to help health care facilities for diagnosing disease with accuracy and speed.

V-TRACE streamlines MRA brain imaging by acquiring four image contrasts in one sequence, providing an imaging application for visualizing slow and fast flow vessels separately and together, as well as the brain tissue surrounding the vessels.

V-TRACE MRA is a dual-echo 3D FE sequence in which the first echo is acquired using Time-Of-Flight (TOF) and the second echo is acquired using Flow Sensitive Black Blood (FSBB). The sequence combines the advantages of both techniques to produce MRA images that depict blood vessels with both high and low velocity.

Toshiba said that the sequence design reduces specific absorption rate (SAR), which is a measurement of heat generated to the body during a MRI. Additionally, the TOF data can be used to evaluate the brain parenchyma. The images produced by the V-TRACE sequence improve the speed and accuracy of diagnosis.

Doug Ryan, vice president of marketing and strategic development at Toshiba, said: “The ability of Toshiba’s V-TRACE MRA sequence to image four contrasts in one sequence allows for greater visualization of blood vessels in the brain, particularly collateral vessels that can be difficult to see with standard MRA sequences. The new sequence allows hospitals to improve workflow and patient care by saving time during MRA imaging.”
